Piro speaks:
Todays comic was HARD. very hard. Why? Because we dont know a lot about Kimiko yet, and her personality is more complex than Miho - you can't get a feel for her personality just from looking at her. I tried very hard to make thier conversation feel natural - and the transitions i had hoped seemed natural.

Piro speaks:
largo is just making an observation, totally unrelated to the conversation between piro and ping. Also, hes seen piro play enough dating sims that he's got the gist of the general nature of what she is saying without understanding it.
